Abstract: 1460779 Baling presses G E CERIBELLI and L CERIBELLI [trading as CERIBEL CARTARIA DI CERIBELLI GIORGIO E CERIBELLI LUIGI] 15 Nov 1974 [16 Nov 1973  4 Sept 1974] 49439/74 Heading B5F [Also in Divisions B3 and B8] A device for wire binding bales of incoherent material or packs, or packages, comprises supply means, not shown, for the binding wire F arranged at positions spaced apart from one another at the external surface of the pack to be bound, means for feeding the pack and binding wire towards wire knotting means arranged in a plane transverse to the direction of feed of the pack, the knotting means comprising at least two wire-guiding means 1a, 1b movable towards and then away from each other in the transverse plane to cause, when moving towards each other, the binding wires to converge to a single location on said transverse plane, the wire guiding means carrying, or forming, a central core or pin 10a, 10b lying substantially in the transverse plane and arranged to extend between the converged wires, the core, or pin, being rotatable to interlace the wires. As shown, the binding device comprises two arcuate members la, 1b which are carried on frames 11a, 11b which are slidable in guide sleeves 12a, 12b and which are driven by piston and cylinder units such as 13b to move the two members 1a, 1b toward and away from each other. Each member 1a, or 1b comprises two parallel plates 2a or 2b the spacing being such that the pairs of plates 2b can pass between the plates 2a. A guide half-ring 5a, or 5b is secured to each of the plates 2a, or 2b in the manner shown for plates 2a in Fig. 2, and a halfgear wheel 7a, 7b is carried respectively between the two half-rings of each pair of plates 2a, 2b so that, when the members la, 1b are in their closed position, Fig. 1, the two half-gears 7a, 7b form an externally-geared whole wheel 7, the latter carrying, on two concentric circumferences, two sets of rollers 8, 9 which engage either side of the axially extending flanges of the half-rings 5a, 5b. The latter support the gear wheel 7 for rotational movement provided either by a gear-drive not shown, or by an endless chain 14 driven by a pinion controlled by a motor 15. The two half-wheels 7a,7b define a free central space 4 therebetween and carry male and female spokes 10a, 10b which extend into the space 4 and which form a single pin when the two half-wheels are in their closed position. In use, a pack, Fig. 6, is moved by a piston P along a tunnel T the binding wires F at the leading end of the pack having been formed into a knot N by the preceding operation and the wires F issuing from either supply means placed in the walls of the tunnel or, from wire rolls, not shown, located outside the tunnel. When the elements 1a, 1b converge behind the preceding, and in front of the oncoming, pack the wires are urged along the curved surfaces of the members 1a, 1b into the centre space 4 with some wires arranged over, and some under, the formed pin (10), Fig. 3, not shown. The gear wheel 7 is then rotated to interlace, and twist, the wires and form a knot N whereupon rotation of the wheel 7 is stopped, and the members 1a, 1b are moved apart to the inoperative position. The eyelet of the knot can either be severed manually or, by the provision of spokes (10<SP>1</SP>a, 10<SP>1</SP>b), Figs. 9-11, not shown, which possess a cutting mechanism. Apparatus for forming bales of material, e.g. paper, comprises a rectangular frame with opposed side walls 35, 35 and 36, 36 which form a chamber 35 which accommodate a presser plate 37 movable vertically to an upper position S by a piston rod 38, and has a hinged hopper 39 for the introduction of baling material, and includes a number of verticallyslidable and spring-loaded pawls 40 which act, to support the pressed-up material. The upper parts 35<SP>1</SP> of the two walls 35 are hinged at 44 and can be moved towards, and away from each other by two screw-threaded tie-rods 45 which are rotatable by hand wheels 47, 47. The top walls 36<SP>1</SP> above the walls 36 could be omitted, as shown, however, half-walls 36<SP>1</SP>, 36<SP>1</SP> are provided, the walls 36 having upward extensions 36a. The apparatus may be enclosed in a chest (51), Fig. 15, not shown.
